The 'perfect body' changes with the times - Marylin Monroe was the perfect body of the 50's and she was a good few sizes larger than the models here.  Many women would be up in arms about this campaign and the comments here make better reading than the article - one says "If you are fat and you don't like it, exercise and make better food choices."  This is true for many of us who could eat and drink less sugar and go to the gym but not every woman has a 'solvable' weight problem.
